Livingston says the letter was to Kennedy’s alleged mistress, Meyer, but it was never sent. His secretary, Evelyn Lincoln, saved the letter.

“Why don’t you leave suburbia for once – come and see me – either here – or at the Cape next week or in Boston the 19th,” the letter reads. “I know it is unwise, irrational, and that you may hate it – on the other hand you may not – and I will love it. You say that it is good for me not to get what I want. After all of these years – you should give me a more loving answer than that. Why don’t you just say yes.”

The letter is just a few sentences long, but is written in large script on four pages. According to WMUR, Meyer was mysteriously killed in 1964.
